We are offering these new Professional Studio Series Noise Free Cables by GLS Audio. They have a 6mm thick, high quality, flexible rubber jacket (not that cheap stiff plastic jacket like others sell). They are heavy duty Noise Free with a Full Metal Quarter Inch TRS Male plug on one end and (2) Full Metal Quarter Inch TRS Females plugs on the other end. These cables have insulated copper conductors plus they are shielded. They are hand wired & hand soldered and have high quality metal ends. You'll notice the newly developed GLS Audio Y-Grip technology. This special injection molded piece was designed to allow 6MM cable to be joined in a Y connection. Normal Y-Cables can't use thick 6mm cable because the connectors can't accept (2) 6MM cables. Typical Y-Cables use 2mm, 3mm or sometimes 4mm cable. Our Y-Grip technology allows 6mm cable with 21g Copper Conductors.
